Behavioral inhibition and amplification during emotional arousal: a comparison of two age groups

This study investigated age differences in the ability to suppress and amplify expressive behavior during emotional arousal. Young and old participants viewed 3 film clips about medical procedures while their behavioral, autonomic, and subjective responses were recorded. Half of the participants viewed all 3 films without additional instructions; the other half was asked to suppress and amplify their behavioral expression during the 2nd and 3rd films. Except for heart rate, suppression and amplification produced similar patterns of autonomic activation. Neither suppression nor amplification had effects on self-reported emotion. There were no age differences in the ability to suppress or amplify emotional expression or in their physiological or subjective consequences. Considering that older people's unregulated reactivity was lower than that of young adults, suppression may have been easier and amplification more difficult for older adults. Voluntary emotion regulation might be one domain of human performance that is spared from age-related losses.     

A two-factor model for predicting when a couple will divorce: exploratory analyses using 14-year longitudinal data

This article examines 14-year longitudinal data and attempts to create a post hoc model that uses Time-1 data to "predict" the length of time the marriage will last. The sample consists of the 21 couples (of 79 studied) who divorced over a 14-year period. A two-factor model is proposed. One factor is the amount of unregulated volatile positive and negative affect in the marriage, and this factor predicts a short marriage length for the divorcing couples. A second factor is called "neutral affective style," and this factor predicts a long marriage length for the divorcing couples. This model is compared to a Time-1 model of ailing marriage in which Time-1 marital satisfaction is used to predict the timing of divorce.     

Autonomic, subjective, and expressive responses to emotional films in older and younger Chinese Americans and European Americans

Previously, the authors found that during idiosyncratic emotional events (relived emotions, discussions about marital conflict), older European American adults demonstrated smaller changes in cardiovascular responding than their younger counterparts (R. W. Levenson, L. L. Carstensen, W. V. Friesen, & P. Ekman, 1991; R. W. Levenson, L. L. Carstensen, & J. M. Gottman, 1994). This study examined whether such differences held when the emotional events were standardized, and whether they extend to another cultural group. Forty-eight old (70-85 years) and 48 young (20-34 years) European Americans and Chinese Americans viewed sad and amusing film clips in the laboratory while their cardiovascular, subjective (online and retrospective), and behavioral responses were measured. Consistent with previous findings, older participants evidenced smaller changes in cardiovascular responding than did younger participants during the film clips. Consistent with earlier reports, old and young participants did not differ in most subjective and behavioral responses to the films. No cultural differences were found.     

Mental health differences among retirees and workers: findings from the Normative Aging Study

Researchers during the past decade have found little effect of retirement on physical health. However, retirement entails a number of losses, and its effect on mental health, as measured by the prevalence of psychological symptoms, is unclear. We examined psychological symptoms in a sample of 1,513 older men, participants in the Normative Aging Study, using the SCL-90-R (Derogatis, 1983). Analyses of variance indicated that retirees reported more psychological symptoms than did workers, even after controlling for physical health status. Exploratory analyses examining the circumstances of retirement found no effects for length of retirement or part-time employment, but did find effects for the timing of retirement. Both early and late retirees reported more psychological symptoms. Late workers (aged 66 and older) reported the fewest symptoms. Reasons for these findings are discussed.     

Risk taking and personality

Comparisons were made of the personality and social orientations of antisocial risk takers, defined as residents in a long-term drug-treatment facility (N = 24); adventurous risk takers, defined as rock climbers (N = 18); and prosocial risk takers, or heroes, defined as policemen and firemen decorated for bravery (N = 21). Measures included substance abuse proclivity, emotional arousability, conformity, moral reasoning, empathy, psychopathy, and sensation seeking. Discriminant analysis identified two functions that correctly classified 98.18% of the sample. Drug-unit residents had high scores on an Antisocial function, characterized by emotionality, depression, psychopathy, substance abuse proclivity, and lower scores on moral reasoning. Rock climbers had high scores on an Antistructural function, characterized by sensation seeking and moral reasoning, the latter reflecting the higher education level of the rock climbers. Neither discriminant function characterized the heroes. Thus, drug-unit residents, rock climbers, and heroes appear to represent both different psychological types and different forms of risk taking.     

Differences in social support among retirees and workers: findings from the Normative Aging Study

Cross-sectional differences between retirees and workers in the importance of coworkers as a source of support, as well as in general quantitative support (social networks and frequency of interaction) and qualitative support (confidants and the perceived reliability of support) were examined. The sample consisted of 1,513 older men (mean age = 61), participants in the Normative Aging Study. Half (56%) were working, and the rest were retired. Slightly fewer retirees than workers reported coworker friends, especially among those who were long-term retirees or who did not work at all in retirement. Whereas similar findings were seen with quantitative support, workers and retirees reported nearly identical levels of qualitative support. However, retirees almost never discussed personal problems with former coworkers. The relevance of these findings for the convoy construct is discussed.     

Multidimensional Locus of Control in Prison Inmates1

This study examined public offenders' generalized expectancies of control as they relate to length of time in prison and behavior within the institution, in order to demonstrate the usefulness of a multidimensional modification of Rotter's locus of control scale with a prison sample. Inmates (N= 145) serving sentences in a large, state prison responded to three locus of control scales designed to measure separately expectancies of internality, of control by powerful others, and of control by chance forces. It was reasoned that if the separation of control into these three orientations is meaningful, then changes in perceptions of control by powerful others should be particularly relevant to the prison experience. As predicted, scores on the Powerful Others scale were significantly related to length of time in prison and number of times punished by solitary confinement.     

Eye blink rate predicts reward decisions in adolescents

The ventral striatum displays hyper‐responsiveness to reward in adolescents relative to other age groups, and animal research on the developmental trajectory of the dopaminergic system suggests that dopamine may underlie adolescent sensitivity to reward. However, practical limitations prevent the direct measurement of dopamine in healthy adolescents. Eye blink rate (EBR) shows promise as a proxy measure of striatal dopamine D2 receptor function. We investigated developmental differences in the relationship between EBR and reward‐seeking behavior on a risky decision‐making task. Increasing EBR was associated with greater reward maximization on the task for adolescent but not adult participants. Furthermore, adolescents demonstrated greater sensitivity to reward value than adults, as evinced by shifts in decision patterns based on increasing potential reward. These findings suggest that previously observed adolescent behavioral and neural hypersensitivity to reward may in fact be due to greater dopamine receptor activity, as represented by the relationship of blink rate and reward‐seeking behavior. They also demonstrate the feasibility and utility of using EBR as a proxy for dopamine in healthy youth in whom direct measurements of dopamine are prohibitively invasive.
